EL2126 is an ultra-low noise, wideband amplifier that runs on half the supply current of competitive parts.
The EL2126 is an ultra‑low‑noise, low‑power wideband amplifier designed for applications such as ultrasound imaging, wideband instrumentation, and communication equipment. It operates from +2.5 V to +15 V, draws only 4.7 mA typical supply current, and is offered in compact 5‑lead SOT‑23 and 8‑lead SOIC packages.
Key specifications include a voltage‑noise density of 1.3 nV/√Hz, current‑noise density of 1.2 pA/√Hz, a -3 dB bandwidth of 100 MHz at a gain of 10, and an operating temperature range of –40 °C to +85 °C. The device features traditional voltage feedback, allowing reactive elements in the feedback loop for filter designs.
